A NVIDIA engineer restructuring some of the printf-related code within the memory resource controller "memcg" statistics printing code to reduce the system time by 11% for dumping those stats...

The Linux kernel developers for months now have been debating proposed guidelines for tool-generated submissions to the Linux kernel. As part of the "tools", the main motivator for this documentation has been around the era of AI and large language models with coding assistants and more. Torvalds made some remarks on the Linux kernel mailing list around his belief in focusing the documentation on "tools" rather than explicitly focusing on AI, given the likelihood of AI-assisted contributions continuing regardless of documentation...

The modern Intel Xe kernel graphics driver was designed from the start to be more broadly compatible with non-x86 architectures given their discrete graphics processors being front and center, unlike the legacy i915 kernel graphics driver being very x86 minded. While this allows running Intel Arc Graphics on ARM or RISC-V, there are some other kinks still being ironed out with using Intel graphics in the non-x86 world. One of those limitations currently being worked through is the lack of GPU firmware updating on non-x86 systems...

Sent out today was the latest batch of drm-misc-next changes to DRM-Next for staging ahead of the upcoming Linux 6.20~7.0 kernel cycle. The reverse-engineered Etnaviv DRM driver for Vivante graphics/NPU hardware has added a new "PPU flop reset" feature gleaned off studying the downstream vendor kernel driver...

To allow for additional security hardening of the Linux kernel, a patch series has been updated more than one year later to link the relocatable x86_64 kernel as Position Independent Executable (PIE) code...

FEX, the open-source emulator for running x86 and x86_64 binaries on AArch64 (ARM64) Linux and that is sponsored by Valve and to be used by the Steam Frame, is out with a new monthly feature release...

For those using a DisplayPort to HDMI dongle currently with the AMDGPU Linux kernel graphics driver may find some higher resolutions / modes unavailable. Fortunately, a fix is on the way for dealing with this situation due to an oversight in the kernel driver...

While for years open-source firmware enthusiasts have been after an open-source Firmware Support Package "FSP" for Intel CPUs and back during Raja Koduri's tenure at Intel it sounded like it might happen, it has yet to happen. But at least with the forthcoming Intel Core Ultra Series 3 "Panther Lake" there are some FSP improvements...

Over the past number of weeks the Dell Pro Max with GB10 has been undergoing a lot of testing at Phoronix. This NVIDIA GB10 powered mini PC with its 20 Arm cores (10 x Cortex-X925, 10 x Cortex-A725) and Blackwell GPU offers a lot of combined compute potential for AI and other workloads. In this article is a look at how the Dell Pro Max with GB10 competes with AMD's Ryzen AI Max+ 395 "Strix Halo" within the Framework Desktop SFF PC.

Next-generation AMD server SoCs -- presumably the AMD EPYC "Venice" on Zen 6 -- is poised to introduce a firmware-agnostic platform configuration platform configuration change method/format. This is This aims to improve server platform interoperability and eliminate redundant configuration efforts for different firmware solutions...

Natalie Vock as one of the open-source developers on Valve's Linux graphics team has been spearheading another big ray-tracing performance improvement for the AMD Radeon Vulkan driver. RADV ray-tracing performance improved a lot in 2025 but it's looking like 2026 could be even more exciting...

A new feature in the queue for likely introduction with the next version of the Linux kernel (Linux 6.20~7.0) is compiler-based context and locking analysis. This kernel code depends on the yet-to-be-released LLVM Clang 22 compiler but can provide some powerful insights to kernel developers...

For those with Acer laptops running Linux on GitHub there has been an out-of-tree driver providing an experimental "acer-wmi-battery" kernel module to allow controlling battery-related features. Now a cleaned-up version of that driver is working on getting into the mainline Linux kernel...

Back in October was an initial proposal for a DRM splash screen client for the Linux kernel that would be primarily useful for embedded systems for rendering a simple "splash screen" when updating the system firmware/software, early display activation at boot, during system recovery, or similar processes. Sent out today was a second revision to the DRM splash screen code...

The Linux kernel's "new mount API" that has been in the kernel since 2019 and recently made rounds for taking 6+ years to land the man page documentation on it will soon be the the only mount API internally within the kernel. Removing the "old" Linux kernel mount API internals is a candidate for the upcoming Linux 7.0 kernel cycle...

The Gentoo Linux project published their 2025 retrospective this week with their many accomplishments, including the recruitment of four more developers and now being up to 31,663 ebuilds and a total of 89GB worth of x86_64 binary packages on mirrors...

The Fedora Engineering and Steering Committee (FESCo) has approved a Fedora 44 change for switching all KDE variants away from using the SDDM display manager to instead use the newer Plasma Login Manager...

The Rust-written Redox OS operating system had an exciting end to the year as it began developing its own native Intel graphics driver...

With some Linux distributions like Fedora Workstation and Ubuntu defaulting to "madvise" Transparent Hugepages (THP) while others like CachyOS and openSUSE defaulting to "always", you may be curious about the madvise vs. always THP difference in modern Linux environments. If so this round of benchmarking is for you in looking at the performance impact of madvise vs. always THP.

LLVM developers and other stakeholders have begun debating the use of pre-compiled headers "PCH" as a means of speeding up the compiulation of the LLVM compiler infrastructure by 1.5x to 2x than with non-PCH builds...
